Ever wondered how to calculate SLA credit for GCP?
Ever wondered how to calculate SLA credit for GCP?
Let’s take a hypothetical situation. How would I calculate an estimated SLA if my application used services deployed on 1,000 Google Compute Engine instances? Assuming that the services were dependent on each other, would the estimated downtime per year of my application be 1,000 * 0.0001 = 0.10 or 10% per year?
SLA is not for only one VM instance, as per official documentation
“For virtual machine instances: Loss of external connectivity or persistent disk access for all running instances, when Instances are placed across two or more Zones in the same Region.”
So the SLA will be tied to a specific zone. If that zone goes down for .01% of the month, that would be like 4:38 minutes.
